Will it hatch??

So guys i just got this new hen i been having them for maybe 5 days and i been watching her lay her eggs and she wouldnt sit on them so i knew right away that she wasnt broody. So about day 2 she has been acting very weird she is ussally active but now she just sits down all day long. So this gave me idea. So once one of my hens layed an egg ( it is not her egg)i got the egg and the hen and put her on top of it and she stayed on it. Do you guys think she will stay on top of it??

In my experience, it takes a while before a hen becomes 100% committed to sitting. I usually leave my broody (I only have one broody that i keep for the sole purpose of sitting) until she has spent two days (and more importantly, nights) on the nest before giving her eggs to set. Just thought i would share that.

I'd suggest that you accumulate a few eggs and set them at the same time under her, rather than one. If she is 100% broody, she should sit without any eggs in the nest.

Sounds like your hen went broody.
A few questions.
What breed is your broody hen. (she may be only sick or lazy and not broody at this point)
Certain breeds are more broody prone than others.
Are your eggs fertile??? Have to ask.

its a red sexlink but when i pick her up the egg was cold why??

If the egg was cold, that suggests to me that your hen was just resting there rather than coddling the egg to keep it warm. JMO
